盾构始发穿越玻璃纤维筋围护结构已经成为一项比较成熟的技术,成功案例也很多,但都是土压平衡盾构。对于泥水平衡盾构,因其工艺特点和设备结构上的不同,为了提高掘进效率,最大限度降低始发风险,有必要优化其穿越玻璃纤维筋围护结构的工艺,减少玻璃纤维筋对环流系统运行的影响,确保盾构始发段掘进的顺利。
Shield originated through the fiberglass reinforcement envelope has become a more mature technology, there are many successful cases, but are the earth pressure balance shield. For mud-water balance shield, due to its different process characteristics and equipment structure, in order to improve driving efficiency and minimize the risk of initiation, it is necessary to optimize its process of crossing the glass fiber reinforcement retaining structure to reduce the impact of glass fiber reinforcement on the circulation system The impact of operation, to ensure that the shield tunneling section of the first successful.
